Title: Multipulse quantization method of multipluse coder
Inventor: TAGUCHI SATORU
IPC: G10L19/04
Filed: 1988-03-28
Abstract: PURPOSE:To improve transmission efficiency by expressing the time position of multipulses within the max. value which previously sets the intervals of adjacent pulses while accumulating said intervals in a time base direction, then reducing the number of the quantization bits of the subsequent pulses in the time base direction when the intervals exceeding the max. value exist. CONSTITUTION:The pulse interval information of the multipulses inputted to a pulse interval deciding device 31 decides whether the respective pulse intervals can be expressed by the preset number of the quantization bits, i.e., 4 bits, or not. Said information is outputted to a pulse amplitude quantization bit setter 33 if said intervals can be expressed by the 4 bits. The information is outputted to a pulse generator 32 if the expression by the 4 bits is not possible. The pulse generator 32 generates the pulse of a pulse amplitude '0' to the position of the max. interval where the pulse position interval can be expressed by the 4 bits in accordance with the information that said interval cannot be expressed by the 4 bits from the pulse interval deciding device 31. The transmission efficiency is thereby improved.

Title: High-pressure discharge lamp lighting device
Inventor: YAMAMOTO MINORU
IPC: H05B41/18
Filed: 1991-04-08
Abstract: PURPOSE:To stabilize discharge by returning the bright point even if the bright point on an electrode shifts from the top of the electrode at instantaneous restart. CONSTITUTION:A high-tension pulse voltage application control means CR1 is provided, which applies high-tension pulse voltage to a high-pressure discharge lamp LA continuously for a certain time even after the lighting of the high- pressure discharge lamp LA. Since the high-tension pulse voltage is applied continuously for a certain time to the high-tension discharge lamp LA even after the lighting of the high-pressure discharge lamp LA, the electric fields become the strongest at the tops of both electrodes of the high-pressure discharge lamp LA, and pulse discharge occurs at the tops. Hereby, the tops of both electrodes get in the conditions that electrons are easy to come out, and even if the bright point does not exist at the tops of the electrode, the bright points recover to the tops. Accordingly, the discharge of the high-pressure discharge lamp LA can be stabilized, and the flicker and the going out of the high-pressure discharge lamp LA can be prevented.

Title: Blast furnace facilities
Inventor: NAKAMURA YUKIO
IPC: C21B7/22
Filed: 1978-06-23
Abstract: PURPOSE: To prevent the air pollution due to the exhaust pressure gas and the generation of noise, by introducing the exhaust pressure gas from the pressure equalizing chamber of the top charger to the low pressure side of the pressure reducer of the gas cleaner through the clean gas breeder pipe, and by removing the dust from the exhaust pressure gas using the electric dust collector.  
     CONSTITUTION: When the pressure is to be released from the upper pressure equalizing chamber 4 of the blast furnace facilities, the pressure release valve 8 is opened, and the three-way switching valve 20 is switched to the direction of the branch pipe 21. Hereby, the pressure of the top gas in the pressure equalizing chamber is reduced to about atmospheric pressure, so that the raw material becomes possible to be charged from the hopper 36. The exhaust pressure gas entered into the clean gas breeder pipe 6 is sent to the electric dust collector 22 where the dust is removed from the gas. After the pressure release is finished, the pressure release valve 8 is closed, and the switching valve 20 is switched to the direction of the blast furnace gas duct 19, so as to switch the course of the clean gas breeder pipe 6. Then, the raw material is charged from the hopper 36 into the pressure equalizing chamber 4. By opening the small bell 2 to open the pressure equalizing valve 10, the gas of the blast furnace gas duct 19 is supplied to the pressure equalizing chamber 4; and when the gas pressure becomes equal to the inner pressure of the lower pressure equalizing chamber 26, the raw material drops into the lower pressure equalizing chamber 26.

Title: Device for treatment of leaves and the like
Inventor: INOUE KENJI
IPC: B65H29/12
Filed: 1985-04-10
Abstract: PURPOSE:To enable leaves and the like accumulated in an accumulating section to be positively held by both No.1 and No.2 conveyor members so as to be discharged by allowing a swaying section which comprises a part of No.1 con veyor member and forms the accumulating section between itself and No.2 conveyor member, to be closed while it is running. CONSTITUTION:When a bank note P which is accumulated in an accumulating section, is discharged, a swaying section 66a is swayed to the side of a high speed conveyor belt 61 which acts as No.2 conveyor belt at the same time, with an electromagnetic solenoid 72 energized, simultaneously a pulse motor is allowed to rotate at high speed. This causes a conveyor belt 66 to run at high speed as No.1 conveyor belt, and allows notes P accumulated in the accumulating section to be conveyed to the direction as shown by an arrow head permitting them to be held by the section contacting with the high speed conveyor belt 61. In addition, driving gears 77 and 78 are meshed each other allowing the note P to be discharged at high speed from a discharging outlet. This configuration does not permit the note to be jammed and to suspend conveying operation as often taken place in the past and enables the note to be stably discharged.
